Abstract
Aim: To develop and assess a protocol proposed for sex determination using frontal sinus height and width measured from two dimensional lateral cephalometric radiographs. Material and Methods: The frontal sinus index was measured on sixty-four cephalometric scans (32 males & 32 females). The maximum height and width of the sinus were measured. The data was tabulated and independent t test was done to determine the correlation to gender. Results: There was a high statistically significant difference between the frontal sinus width measured between male and female groups. The p value for width was found to be 0.02 which is significant. Conclusion: Measuring the frontal sinus height and width by the proposed protocol is promising. Multicentric study is recommended to reach a solid evidence-based result. Also testing the reliability of the standardization protocol is recommended by applying it on multiple drawn sinus borders by multiple experienced radiologists.
